Contesting with N1MM on Linux

N1MM+ has been the go-to contest logger for many hams and, thanks to its networking features, also clubs. Sadly, it's only for Windows, it's closed-source and the bugs (whether in N1MM or Wine) don't make it any more fun.

Setting up Wine

1. Install any decently recent flavour of Wine. Usually the one provided by your distro's package manager is fine.
2. Install winetricks.
3. Set the required environment variables. To work inside this wineprefix (which is, in short, a self-contained "fake" "Windows" "installation"), you need to specify its path inside every newly opened terminal window.
